A view-based decision mechanism for rewards in the primate amygdala

F Grabenhorst, A Ponce-Alvarez, A Battaglia-Mayer… - Neuron, 2023 - cell.com
Primates make decisions visually by shifting their view from one object to the next,
comparing values between objects, and choosing the best reward, even before acting. Here …

How Many Neurons Does it Take to Approximate the Maximum?

I Safran, D Reichman, P Valiant - Proceedings of the 2024 Annual ACM-SIAM …, 2024 - SIAM
We study the size of a neural network needed to approximate the maximum function over d
inputs, in the most basic setting of approximating with respect to the L 2 norm, for continuous …

A multi-stage anticipated surprise model with dynamic expectation for economic decision-making

HK Chan, T Toyoizumi - Scientific Reports, 2024 - nature.com
There are many modeling works that aim to explain people's behaviors that violate classical
economic theories. However, these models often do not take into full account the multi-stage …

An interactive cortical architecture for perceptual organization by accentuation

D Domijan, M Marić - Neural Networks, 2024 - Elsevier
Accentuation has been proposed as a general principle of perceptual organization. Here,
we have developed a neurodynamic architecture to explain how accentuation affects …

[HTML][HTML] Accentuation, Boolean maps and perception of (dis) similarity in a neural model of visual segmentation

D Domijan, I Ivančić - Vision research, 2024 - Elsevier
We developed an interactive cortical circuit for visual segmentation that integrates bottom-up
and top-down processing to segregate or group visual elements. A bottom-up pathway …

with each option, as well as subjective preference for risky/safe alternatives. Inaccurate …

An economic decision-making model of anticipated surprise with dynamic expectation

HK Chan, T Toyoizumi - arxiv preprint arxiv:2108.12347, 2021 - arxiv.org
When making decisions under risk, people often exhibit behaviors that classical economic
theories cannot explain. Newer models that attempt to account for these irrational behaviors …
